Ring size guide

Lay a ring you own flat on the circle and slide until it sits just inside it — or set its inner diameter directly.

Measure the inside of a ring that already fits — inner edge to edge — with a ruler in mm, then set it below. No ring handy? Try Measure your finger.

Between sizes? Always choose the larger size. Fingers are slightly bigger in the evening — measure then for the best fit.

Method 1 — Use an existing ring

Find a ring that fits the intended finger comfortably.
Place it flat and measure the inner diameter (inside edge to inside edge) in mm.
Enter that measurement in the Measure a ring tab.

Method 2 — Wrap and measure

Wrap a thin strip of paper around the base of your finger.
Mark where it overlaps — measure that length in mm (your circumference).
Divide by 3.1416 (π) to get your diameter, then use the Measure a ring tab.

Tip: Middle finger sizes typically run half a size larger than the ring finger. If between sizes, go up. Measure in the evening — fingers are slightly larger then.

At a glance

A marquise lab grown diamond nature-inspired engagement ring from Signora Jewels.

The photographed design centers a 2.00 ct marquise measuring approximately 11.5 × 6.3 mm in a six-prong setting, with 18 round accent diamonds totaling approximately 0.14 ct through the floral shoulders. Approx. 2.14 ct total.

Made to order in 11 metals: silver, 9K/14K/18K gold (yellow, white, rose) and platinum.

Each metal color is shown in the photos. Choose a 1 ct, 1.5 ct, 2 ct, 2.5 ct, 3 ct, 3.5 ct, 4 ct or 4.5 ct center and your preferred metal from the options on this page.

Signora Jewels sets the 11.5 × 6.3 mm marquise between two sculpted floral shoulders rather than a conventional straight pavé band. Six prongs hold the photographed 2.00 ct center, with dedicated contact at both pointed tips, while metal petals and leaves spread outward on either side.

Eighteen small rounds add approximately 0.14 ct through the shoulder design. The floral sections reach about 5.20 mm near the center before narrowing into a 2.30 mm lower shank, and the reference setting stands approximately 8.00 mm high.

Design highlights

Marquise center options: 1 ct, 1.5 ct, 2 ct, 2.5 ct, 3 ct, 3.5 ct, 4 ct or 4.5 ct
2.00 ct reference center measuring approximately 11.5 × 6.3 mm
18 round accent diamonds totaling approximately 0.14 ct
Six-prong center setting with protection at both marquise tips
Sculpted flower petals and leaves worked directly into the shoulders
Approx. 5.20 mm shoulders tapering into a 2.30 mm lower shank

The flowers are built from metal first, diamonds second. Raised petals frame the center, leaves project into the open spaces, and small rounds sit between those forms rather than covering the entire shoulder in pavé.

About Lab Grown Diamonds

The marquise reference center measures approximately 11.5 × 6.3 mm at 2.00 ct. Its long outline ends in two vulnerable points, so this six-prong arrangement places protection at both tips while additional prongs support the long sides. The 18 smaller rounds add approximately 0.14 ct without changing the center's elongated outline.

Metal, Care & Fit

The reference construction uses approximately 6.40 g of 18K gold before the diamonds are set. Yellow and rose gold make the individual petals and leaves easier to distinguish; white gold and platinum keep the accent settings closer in tone to the stones. Clean around the flower recesses and beneath the center with warm water, mild soap and a soft brush.

FAQ

How are the pointed ends of the marquise protected?
The six-prong setting includes contact at both pointed ends of the center. Those end prongs protect the most vulnerable areas of the approximately 11.5 × 6.3 mm reference diamond.

Where are the 18 accent diamonds set?
Eighteen round diamonds totaling approximately 0.14 ct run through the flower-and-leaf shoulders. They sit between sculpted metal forms rather than forming one continuous straight pavé row.

How wide are the floral shoulders?
The sculptural shoulder area reaches approximately 5.20 mm near the center before narrowing into a 2.30 mm lower shank. Individual petals and leaves account for much of that extra width.

How high does the 2 ct reference center sit?
The photographed setting is approximately 8.00 mm high. The center head scales with the selected diamond weight while retaining the floral shoulder structure.

How should I clean around the flower and leaf details?
Use warm water, mild soap and a soft brush from the top and underside. Work gently around the 18 small diamonds and inside the recessed petal and leaf sections where residue can collect.

Answers last updated August 2, 2026

When will my order ship?

Standard listed pieces are made to order with an estimated dispatch of 7 business days. Use the product-page estimate when it is more specific and the timing confirmed after ordering. Delivery timing begins after dispatch and varies by destination and carrier service. Fully custom commissions follow the production schedule confirmed with their approved specifications or CAD.

When is insured worldwide delivery free?

Orders of US$500 or more receive free express, insured and tracked worldwide delivery. Below US$500, express, insured and tracked worldwide delivery is charged at the fixed rate shown at checkout.

Will I have to pay import duties?

For every destination available at checkout, Signora prepays applicable import duties and import taxes. Customers should not be asked to pay those import charges again on delivery.

What certificate comes with my jewelry?

Every finished piece includes a Signora Jewelry Certificate. Each selected individual lab-grown center or primary diamond of 0.50 ct or above includes an IGI grading report. Below 0.50 ct, IGI can be arranged by custom request. Custom moissanite and gemstone selections include GRA documentation, with the exact scope confirmed in the approved specifications. The product page or approved specifications state the exact laboratory, report type and scope.

Can I return a made-to-order listed design?

Standard listed products are eligible for return within 30 days after carrier-recorded delivery when unworn, unused and in their original condition, with the original packaging and included documents. Normal listed choices such as metal, stone carat, chain or bracelet length, an extended ring size, or complimentary engraving do not by themselves make an item Final Sale. A sale or discount also does not imply Final Sale; only an item explicitly classified as Final Sale follows the non-returnable exclusion.

How are fully custom orders handled?

A fully custom commission is different from a listed made-to-order design. After its specifications or CAD are approved, a normal change-of-mind return does not apply. Manufacturing defects remain reviewable. Signora may accept an exceptional non-defect return case by case; documented labor and genuinely non-recoverable costs may be deducted, but these deductions are not a restocking fee.
